Not a good graphics card at all. It's intended for movie playback only, not gaming.
The very minimum I'd recommend for WoW is the 6670... it's a low end gaming gpu but it'll get you at least good settings, probably high on WoW. Many times more powerful than a 5450.

Your cpu isn't the best for 25m raids either... athlon II's aren't very strong. Shouldn't matter as much if you do 10m's though... and may still be playable in 25m's.

If the radiance of a thousand suns were to burst at once into the sky, that would be like the splendor of the Mighty One... now I am become Death, the Destroyer of Worlds.

Yes its a HP, model # p6754y....ive been playing with the older model of that vid card and getting decent (30+) fps and sometimes lower depending on where im at in game, i was hoping to see improvement with this new vid card before i opened it... i dont lag much in 25ms and rarely in 10ms, but was looking to increase overall performace. any suggestions on a better vid card in that same price range or slightly higher

First, I want to say that everyone in the above postings is correct; the 5450 just isn't designed for gaming although it can with very limited results. Second, you might need to think about a slightly larger budget when it comes to buying a gpu. In a typical gaming computer setup, the GPU is usually the most expensive item versus processor (you don't need top of the line), hard drive (SSD has yet to be a necessity), memory (higher speed memory doesn't always equate to faster gaming). Here's my recommendation for a gpu that shouldn't break the bank if your into the AMD side of the force:

You can actually have a card for LESS money that will do far better with WoW. I run this in one of my rigs and running on either high or ultra I only see drops down to 45fps when doing 25m. Any other time I am usually hanging out at 54-60fps. The only momentary issue I ran into was going for the "Many Welps!" achieve where my framerate dropped really low for a few seconds but was fine after that. Its a solid performer for the price and it is certainly good enough for WoW, but spending more means getting to play other games (or future MMOs) without having to worry about replacing your GPU in order to keep a good frame rate.

SO with this Pre made PC i have, what would Vid car would give me the best FPS and performance without changing my power supply? and how can i look up the specs for alot of these cards, i cant find any in depth specs for the 5450 nor can i overclock it.

The best video card you can purchase without having to change the power supply is going to be Radeon HD6570 $64.99

You can run a 6670 safely on that power supply... it only has a 63 watt tdp. It's significantly better than a 5570.. well worth the extra $20 imo... though a 5570 will still be playable on reasonable settings.

Rule of thumb is to buy whatever was equivalent to the lifecycle of the hardware in your system and ask yourself whether it was entry, mid, or high end to avoid a bottleneck and save money.

It's also important to know what resolution you intend to play on and, for the love of god, don't just assume a cheap card is good because it has a lot of memory. That is the oldest trick in the book when it comes to graphic card sales.
